I mean, I have been wronged by an ex too, and was deeply hurt. I totally get the anger, and wishing my ex was eaten by a shark has ran through my head, among other things.
But at its core, I think of my ex rotting in hell, paying for the things he's done, in essence paying the price for what he did for me, and it doesn't make me laugh. I really worry about him, and all I can do is pray God will call to him.
Maybe I'm taking this too seriously and being a kill-joy. I apologize if that's the case.
